PROBLEM TO BE SOLVED: To provide a flex-rigid printed wiring board capable of having improved thickness accuracy, and being easily bendable at flex portions. SOLUTION: A plurality of rigid portions 1 are integrated with each other through the flex portions 2 to form this flex-rigid printed wiring board A. The epoxy resin layer 5 of a resin sheet 6 with metal foil which is formed by laminating the metal foil 3, a polyimide film 4, and the epoxy resin layer 5 in this order is superposed on a flexible board 7, and the resin sheet 6 with the metal foil is bonded to the flexible board 7. The metal foil 3 in a prescribed area is removed in a prescribed pattern shape to form a conductor circuit 8, and the rigid portions 1 are formed by laminating rigid boards 9 in this area. The metal foil 3 in the area other than the prescribed area is removed to form the flex portion 2. COPYRIGHT: (C)2010,JPO&INPIT |
